The present invention relates to a spotlight bracket for a false ceiling or false wall constituted by a stretched sheet fastened, along its edges, to a support fixed to the wall or ceiling.
False ceilings are already known which comprise, on the one hand, a horizontal frame fixed to the upper part of the walls of a premises, this frame being formed by an outer longitudinal member itself constituted by butt-jointed sections and, on the other hand, a sheet stretched horizontally within this frame, this sheet being constituted by a sheet of plastics material or a fabric cloth. The sheet is maintained stretched due to the fastening, on the longitudinal member, of an edge integral with the sheet, forming to some extent a "harpoon", this edge presenting in cross section the form of a hook hooking on a shoulder of the longitudinal member.
Such known false ceilings are often used with a spotlight which is housed in a support or bracket fixed to the ceiling and/or to the wall between them and the sheet. Where a spotlight is mounted, the sheet is cut out so as to present an opening of diameter corresponding substantially to that of the spot, in order to allow the room in which the false ceiling or the false wall is mounted, to be illuminated.
The present invention relates to a spotlight bracket of particularly simple design which allows simple assembly whatever the implantation of the installation.
To that end, this spotlight bracket for use in a false ceiling or false wall constituted by a stretched sheet hooked, along its edges, to a support fixed to the wall or to the ceiling, comprises two parts adjustable with respect to each other, namely an upper part fixed to the ceiling and a lower part adjustable in height and in inclination with respect to the fixed upper part.
The stretched sheet may be connected to oppositely facing walls by any suitable conventional means. One such example of a suitable means is shown in Scherrer, U.S. Pat. No. 4,408,433. The aforesaid U.S. patent also refers to other prior art disclosing material or cloth maintained stretched inside a frame which is fixed to the top of the walls of a room.
The invention will be more readily understood on reading the following description with reference to the accompanying drawings, in which:
FIG. 1 is a view in vertical section of a spotlight bracket mounted above a stretched sheet constituting a false ceiling, according to the invention.
FIG. 2 is a view in perspective of the spotlight bracket of FIG. 1.
FIG. 3 is a view in elevation of the bracket used for assembling a spotlight in an inclined panel.
Referring now to the drawings, FIG. 1 shows a spotlight bracket 1 according to the invention which is disposed between a ceiling 2 and a stretched sheet 3 (schematically shown) extending horizontally and constituting a false ceiling. The spotlight bracket 1 according to the invention comprises two parts adjustable with respect to each other, namely an upper part 4 fixed to the ceiling 2 and a lower part 5 which is adjustable in height and inclination with respect to the fixed upper part 4. The upper part 4, in the form of a downwardly open fork-joint, comprises an upper horizontal web 6 which may be constituted by a piece of wood, this web 6 being fixed to the ceiling 2. The web 6 is pierced with a hole 7 for the passage of an electric cable 8. The web 6 is fast, at its two ends, with two vertical arms 9, 10 extending downwardly.
Furthermore, the adjustable lower part 5 which is also in the form of an upwardly open fork-joint, comprises a lower horizontal base plate 11 fast with two opposite vertical arms 12 and 13 extending upwardly and which tighten on arms 9,10 of the fixed upper fork-joint 4. The base plate 11 which may have a contour of any form, for example polygonal as shown in FIG. 2, is pierced at its centre with a hole 14 for the passage of a bulb 15 of the spotlight borne by bracket 1. The stretched sheet 3 is for its part also pierced with a hole 16, in registry with hole 14 of the base plate 11, and it preferably bears, on its upper face and around hole 16, a reinforcing washer 17 glued thereto.
The vertical arms 9, 12 on the one hand and 10,13 on the other hand, are assembled together so as to form assemblies adjustable in length and in inclination. Such adjustments are obtained thanks to the presence of oblong vertical slots 18 in arms 9,10,12,13 and of locking elements 19, for example of the butterfly nut type, engaged in the oblong slots 18.
FIG. 3 illustrates the use of a spotlight bracket according to the invention when the spotlight is to be placed in an inclined plane. In that case, the lower part 5 of the bracket 1 is inclined by the appropriate angle with respect to the upper vertical part 4 fixed to ceiling 2.
A tube 20 may possibly be disposed inside the bracket 1, in abutment on plate 11 and surrounding the spotlight in order to form a screen with regard to the light radiated upwardly.
